In roller burnishing is process, a hard and highly polished roller is pressed against a rotating component.   This results in the plastic flow of material from the peaks of surface irregularities into the valleys, thereby reducing the surface roughness. The pressure applied causes the cold working of the component’s surface which in turn improves micro-hardness, induces compressive stresses and refines the microstructure. This improvement in properties has a positive impact on the surface...

As semiconductor processes continue to be complex and the number of production steps is increased, a single floor line often comes to have not enough capacity to cover such production. Therefore, in recent years, multiple floors or multiple lines have been combined into a single Fab and this increases inter-floor (or inter-line) delivery. This increase in inter-floor delivery leads to a bottleneck, causing significant production loss. In this paper, we proposed operation policies of inter-floor...

Friction phenomenon in gear systems has been the subject of several studies in the last decades, and it is still a very active area of research. The complexity of the friction phenomenon, occurring when two teeth are in contact during the meshing phase, results in the fact that, many gear key parameters vary simultaneously essentially the velocities, the friction coefficient and the transmitted load. Due to the rising of fuel prices and the increase in energy demand on one hand, and the...

The main aim of any design should not only be focused on ‘Customer satisfaction’ but also ‘Customer safety’. Following this, the number of accidents have been witnessed only due to ill lighting facilities provided in an automobile. Keeping this drawback in view “Steering Controlled Headlight System” has been proposed which would hopefully turn out to be a boon to the people driving through the curved roads during night times. Automobiles are controlled by steering system. The...
